The Miscellaneous Human Sexuality Periodicals collection contains mostly small runs of periodicals on a variety of human sexuality subjects, including lesbians, gay men, bisexuals, transsexuals and transgender people, AIDS, feminism, and gender and sexual identity. Titles may be published in the United States or internationally. The collection also includes conference brochures from the 1963 and 1964 conferences of ECHO, East Coast Homophile Organizations. Bringing together the Daughters of Bilitis, the Janus Society, and the New York City and Washington, DC chapters of the Mattachine Society, ECHO was the first attempt to create a national coalition of organizations focused on equal rights for lesbians and gay men.
